Subject: [PATCH v6 24/41] ARM: dm644x: add new clock init using common clock framework
Date:   Sat, 20 Jan 2018 11:14:03 -0600
Message-Id: <1516468460-4908-25-git-send-email-david@lechnology.com>
In-Reply-To: <1516468460-4908-1-git-send-email-david@lechnology.com>
References: <1516468460-4908-1-git-send-email-david@lechnology.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This adds the new board-specific clock init in mach-davinci/dm644x.c
using the new common clock framework drivers.

The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.

Also clean up the #includes since we are adding some here.
